Granted: 1990-05-23
Abstract: The bleaching chemicals are added to the pulp immediately after heating of the raw pulp thickened to more than 20% by weight and immediately prior to a dispersing process. This is carried out in a high-speed, high-efficiency disperser, where the heated, thickened pulp is forced through a plurality of narrow slits in a disperser lining and is exposed to strong shearing, impact and kneading stresses. In this way, the dispersing process is reduced to a time period less than 3 seconds, preferably about 1 second or less. As a result, the total time required for reductive bleaching is reduced to less than 15 seconds and no further measures are required for displacing and excluding air from the system. The method can also be advantageously used with oxidative bleaching at reduced reaction time requirements. A high dispersing temperature in the region of 40 DEG C. to 110 DEG  C., preferably about 95 DEG  C. is possible and there are essentially simultaneously carried out the bleaching and dispersing actions without the need for separate dispersing stages and large reaction towers and pumps.

Title: Copying attachment for modification (distortion) of typons
IPC: G03B27/16
Filed: 1989-11-23
Granted: 1992-05-13
Abstract: The copying device for the modification (distortion) of film patterns, which are arranged on a film to be exposed, comprises a light source 2 which is movable over the film and film pattern. A relative movement between the film pattern and the film is effected in a known manner in the axial direction of the movement of the light source in order to carry out the desired elongation or compression. Further, a slit or line diaphragm is provided, preferably in the form of a collecting lens 6, which extends transversely relative to the movement direction of the light source and is movable along with this. According to the invention, the light source 2 is substantially enclosed by a light collecting foil 3 (as is commercially available under the trademark "LISA" of the firm BAYER AG), one edge of the foil extends parallel to the line diaphragm 6 and is adjacent to it. Accordingly, a point light is radiated in spite of excitation by means of a scattered light in the edge axis. Due to the high efficiency, the collecting lens can be sharply stopped down, i.e. a very narrow light slit is usable, so that a great depth of focus is formed and a shadow-draw effect is prevented.
